基于双DSP低电压大电流变换器的模糊PID控制
Fuzzy-PID Control for the Buck+Half-Bridge(d=50%)Converter based on DSP
【摘要】 讨论了带同步整流Buck+半桥(d=50%)低电压大电流DC/DC变换器的拓扑结构、工作原理及其优缺点。由于该变换器结构复杂、数学模型阶次高,给控制电路带来一定的困难,为此采用模糊PID控制策略进行控制,仿真与实验结果表明该控制方案可行且性能优越。
【Abstract】 The topology,the principle and the characters of the Buck+HalfBridge(d=50%) low voltage large current converter are discussed.Because of the complexity and the high grades of the mathematic model of the converter,which makes the control difficult,here the FuzzyPID control strategy is used.Simulation and experiment results indicated that the controller presented above is feasible.
